Romania, Latvia, Serbia, Croatia, Belarus and Ukraine will be available next week. Laws regarding SMS services in these countries are stricter than in the others, so that's why it takes few more days to get the service available. We're working on it

We're working on getting Lithuania on the list. Lithuania has stricter regulations than other countries, so that's why it's going to take little longer. We're working on it. I'll post here when Lithuania has SMS boost

Unfortunately we've received information that Serbia is not available anytime soon. Don't lose your hope, though. There's hope to get Serbia up the speed in 2011

@ Silent
Boost is assigned to specific IP address. You shouldn't change the IP in the middle of Boost period.

@ SAMPCam
Support for U.S. and Canada is unknown. At the moment it seems there won't be support in the near future either. SMS services in U.S. don't have this kind of similar free service as Fortumo in Europe. For example Clickatell has $100 startup fee and $25/mo.

The basic service is free. Anybody can get their server listed at Setti. Anybody can try the end user service for free. If you want to Boost, then you know what you're getting. There is no refund, which should be quite clear considering the price also
